Skid Steer Attachments Hydraulic Flow Guide (GPM): How to Choose the Right Attachment

Choosing the right skid steer attachment goes beyond size and compatibility. One of the most overlooked factors is hydraulic flow (GPM), and selecting the wrong hydraulic setup can lead to poor performance, slower operation, or unnecessary wear.

This guide explains how hydraulic flow works and how to match your skid steer to the right attachment.

What Does Hydraulic Flow (GPM) Mean?

GPM (Gallons Per Minute) measures the amount of hydraulic oil your skid steer sends to an attachment.

Hydraulic-powered attachments rely on this flow to operate correctly. The more hydraulic flow available (within specification), the more power-intensive attachments can perform efficiently.

Think of it this way:

• Low GPM → lighter-duty attachments

• Higher GPM → more demanding applications

Hydraulic pressure (PSI) also matters, but GPM is usually the first number people check when choosing attachments.

Standard Flow (Typical: 17–25 GPM)

Standard-flow machines are commonly used for general construction, landscaping, and farm work.

Recommended attachments:

• Buckets

• Pallet forks

• Grapples

• Augers

• Utility trenchers

• Light brush cutters

Best for:
✔ Everyday operations
✔ Lower operating costs
✔ General attachment use

High Flow (Typical: 26–40+ GPM)

High-flow systems provide more hydraulic output for demanding jobs.

Recommended attachments:

• Forestry mulchers

• Heavy-duty brush cutters

• Snow blowers

• Cold planers

• Industrial trenchers

Best for:
✔ Heavy-duty work
✔ Faster attachment performance
✔ High-production environments

Common Attachment Hydraulic Requirements (General Reference)

Always verify exact manufacturer specifications.

How to Check Your Skid Steer Hydraulic Specs

Before ordering an attachment, check:

1. Operator’s Manual

Locate hydraulic specifications.

2. Machine Identification Plate

Many machines display hydraulic ratings.

3. Manufacturer Specifications

Confirm:

• Hydraulic Flow (GPM)

• Hydraulic Pressure (PSI)

• Standard or High Flow

4. Dealer or Equipment Supplier

Ask for confirmation before purchase.

Common Mistakes When Choosing Attachments

Buying Based Only on Physical Fit

Even if the attachment mounts correctly, hydraulic requirements may not match.

Ignoring Hydraulic Pressure

Flow and pressure must work together.

Assuming More GPM Is Always Better

Too much hydraulic flow can also affect attachment operation.

Example: Matching Attachments to Jobs

Farm and Property Maintenance

Recommended:

• Grapple

• Standard-flow auger

• Utility bucket

Land Clearing

Recommended:

• High-flow brush cutter

• Forestry mulcher

Winter Operations

Recommended:

• High-flow snow blower

Frequently Asked Questions

Can I run a high-flow attachment on a standard-flow machine?

Usually not. Performance may be reduced or the attachment may not operate correctly.

Is higher GPM always better?

No. Attachments are designed for specific hydraulic ranges.

Where can I find my skid steer GPM?

Check the machine manual or manufacturer specifications.

Final Thoughts

Understanding hydraulic flow helps you select attachments that perform efficiently and last longer.

Before purchasing, confirm your skid steer’s GPM, PSI, and flow type to ensure compatibility.
